Let's start with the obvious: if you are not already a fan of the lysergic antics of Tim and Eric Awesome Show, Great Job, the chances of its fifth season (a.k.a. Season Cinco) bringing you into the fold are slim. The show, which peels a kaleidoscopic fisheye at low-rent television and advertising via short, stream-of-consciousness sketches, is almost doggedly determined to polarize viewers--if you don't find male lactation, an adult onset of puberty, monster crows, and a dance craze based on spanking hilarious, you're simply out in the cold regarding Awesome Show, Great Job. However, if Tim Heidecker and Eric Wareheim's brand of humor strikes you, like many viewers and critics, as a fresh and irreverent force on television, you'll find much to like in Season Cinco. The 10 episodes featured on the disc feature both recurring segments, like "Brule's Rules," with John C. Reilly as the perennially uncomfortable TV medico, and the return of Zach Galifianakis's deranged actor Tairy Greene, whose ridiculous oeuvre is made available through the Tairy Greene Machine. Elsewhere, Tim falls victim to "Crows" in an homage to the cult film Birdemic: Shock and Terror, and the boys bring nausea to the holidays in "Man Milk," which finds them handing out their own surprise lactation as gifts. In its best moments, Tim and Eric approach the jaw-dropping lunacy of Monty Python and Mr. Show, and the wealth of guest stars, which include Will Ferrell, Paul Rudd (performing a truly astonishing dance), Fred Armisen, Rainn Wilson, and 30 Rock's Jack McBrayer help to sell the material (as do such curious cameos as Patrick Duffy, Karen Black, and Danny Trejo). If there's a downside to the season it might be the somewhat dark tone in some sketches, as promised by Wareheim in 2009 interviews, but gags about child clown molestation in "Stuntmen" will be a step too far for some. But again, if you're a devoted fan, you accept such trips into the deep end of the comedy pool as part and parcel of the Tim and Eric experience. If you're up for navigating the deliberately confusing screen menus, you'll find extended and deleted scenes, karaoke tracks for the season's musical numbers, and a surprisingly heartfelt tribute to actor Richard Dunn, a fixture of the show since its first episode, and who died in June 2010. --Paul Gaita
